Best practice for connecting Power BI to Azure AD?

Hi,

I am trying to use employee data in Active Directory for a report and we are querying Microsoft Graph for this. We tried following the method in the blog below for connecting and it worked fine till I tried to schedule refresh. The current “anonymous” connection is not allowing the report to update.

I was wandering if someone can help with ways to authenticate Power BI with Microsoft Graph (specifically Azure AD endpoint) using a user account or at the very least the best practice for connecting Power BI to Azure AD?

Thanks
